ACKNOLEDGEMENTIt is with great pleasure that I find myself
penning down these lines to express my sincere thanks to various
people who helped me a long way in completing this project.
The harmonious climate in our school provided proper guide for
preparing the project. It was a privilege to have been guided by
our computer teacher.
Thanks to all my classmates who helped me during development of
this project with their constructive criticism and advice.

OVERVIEWThis is a Shop Management software which can be used by
Store Keepers to manage product details available in their store
and for Billing Purpose. In this application, we allow store
keepers to enter the details of the products available in their
store, to view them, to delete them, and prepare bills. Features
provided by this project are as follows:
1. Storing details of products: All the details of the products
like product no., product name, price can be stored in the
database.2. Display product details: Store keepers can view all the
details of the product available in their store at any time.3.
Delete: This feature is also supported by this project. The list of
the products can be deleted any time and can be re created as per
their needs.
4. Billing : With the help of this feature user can get the
whole list of the products on the billing menu, so the user just
need to enter the product no. and all the details of that product
will automatically be displayed on the bill, with the total amount
that the customer needs to pay.INTRODUCTION TO C++The C++
programming language was developed at AT&T bell laboratories in
the early 1980s by Bjarne Stroustrup. He found C lacking for
stimulations and decided to extend the language by adding features
from Simula 67 which was one of the earliest object oriented
languages. The name C++ was coined by Rick Mascitti where ++ is the
C increment operator. Ever since its birth, C++ involved coping
with problems encountered by users and through discussions at
AT&T. However, the maturation of the language is attested to by
two events:
1. Formation of ANSI C++ committee.2. Publication of The
Annotated C++ Reference Manual by Ellis & Stroustrup. C++ is
one of the most popular programming languagesand is implemented on
a wide variety of hardware and operating system platforms. As an
efficient compiler to native code, its application domains include
systems software,application software, device drivers, embedded
software, high-performance server and client applications, and
entertainment software such asvideo games.FEATURES OF C++
PROGRAMSIn C++, you can develop new data types that contain
functional descriptions (member functions) as well as data
representations. These new data types are calledclasses. The work
of developing such classes is known asdata abstraction. You can
work with a combination of classes from established class
libraries, develop your own classes, or derive new classes from
existing classes by adding data descriptions and functions. New
classes can contain (inherit) properties from one or more classes.
The classes describe the data types and functions available, but
they can hide (encapsulate) the implementation details from the
client programs.
You can define a series of functions with different argument
types that all use the same function name. This is calledfunction
overloading. A function can have the same name and argument types
in base and derived classes.
Declaring a class member function in a base class allows you to
override its implementation in a derived class. If you use virtual
functions, class-dependent behavior may be determined at run time.
This ability to select functions at run time, depending on data
types, is calledpolymorphism.Every C++ program must have a function
named main (). Program execution begins at main () and continues by
sequentially executing the statements within main (). A program
terminates normally following execution of the last statement of
main (). Curly braces ({&}) is used to express grouping of
statements in C++. Every executable statement in C++ must be
terminated by a semicolon (;).
OOP CONCEPTS IN C++
The Object Oriented Programming has been developed with a view
to overcome the drawbacks of the conventional programming
approaches. The OOP approach is based on certain oncepts that help
it attain its goal of overcoming the drawbacks or shortcomings of
conventional programming approaches. These general concepts of OOP
are given below:
DATA ABSTRACTIONIn C++, you can develop new data types that
contain functional descriptions (member functions) as well as data
representations. These new data types are calledclasses. The work
of developing such classes is known asdata abstraction. You can
work with a combination of classes from established class
libraries, develop your own classes, or derive new classes from
existing classes by adding data descriptions and functions. New
classes can contain (inherit) properties from one or more classes.
The classes describe the data types and functions available, but
they can hide (encapsulate) the implementation details from the
client programs.
INHERITANCE
It is the capability of one class of things to inherit
capability or properties from another class. Inheritanceallows one
data type to acquire properties of other data types. Inheritance
from abase classmay be declared as public, protected, or private.
This access specifier determines whether unrelated and derived
classes can access the inherited public and protected members of
the base class. Only public inheritance corresponds to what is
usually meant by "inheritance". The other two forms are much less
frequently used. If the access specifier is omitted, a "class"
inherits privately, while a "struct" inherits
publicly.POLYMORPHISM
It is the ability for a message to be processed in more than one
form. Declaring a class member function in a base class allows you
to override its implementation in a derived class. If you use
virtual functions, class-dependent behavior may be determined at
run time. This ability to select functions at run time, depending
on data types, is calledpolymorphismSOME IMPORTANT DATA TYPES IN
C++ARRAYS
Arrays refer to a named list of a finite number n of similar
data elements. They maybe 1-dimensional, 2-dimensional or
multi-dimensional.Example : float A[30];
FUNCTION
It is a named part of program, which can be invoked from other
parts of the program as often needed.POINTERIt is a variable which
holds a memory address. This address is usually the location of
another variable in memory.
Example : char *ptr;
CLASS
It represents a group of similar objects. A class describes all
the properties of a data type and an object is an entity created
according to that description.
